THREAD CLEANING DEVICE Filed Feb. 26, 1938 Patented Aug. 16, 1938 UNITED STATES PATENT OFFICE 3 Claims.

This invention relates to thread cleaners and the like, for removing slubs, knots, wax-like accumulations and other imperfections from thread and yarn in winding and other machines,

when the thread or yarn is wound on cops, cones, bobbins or other containers. It aims to provide an improved device for that purpose.

In the drawing of the embodiment of my invention selected for illustration and description ,lll herein:

Fig. l is a front elevation;

Fig. 2, a side elevation;

Fig. 3, a plan, partly broken away;

Fig. 4, a plan of one of the thread cleaning disk elements;

Fig. 5, a partial plan, parts being broken away, of a modified form of the structure of Fig. 4; and

Fig.6, a plan of a modified form of construction, with a single thread cleaning edge.

Referring first to Figs. 1, 2, 3, my novel thread cleaner comprises a base or back plate I, of suitable size and material, as metal, provided on its upper end at the rear with convenient means for securing the device to a suitable member of the machine on which it is used, such means herein being jaws 2 of proper size and shape to receive a bar or rod 3, and a locking screw 4 threaded into one of the jaws for locking the device to the supporting rod.

The base or back plate has, at its ends, a suitable thread guide 5 of any desired type.

At a proper point between its two ends, the plate 5 is provided with novel cleaning member supporting means, as suitable arms 6 extended forwardly and then laterally toward each other, which receive behind them the tongue I of a cleaning member carrying bracket 8.

The bracket, at its rear edge, may be beveled forwardly a little as at 9, and the tongue I may also be bent forwardly, or otherwise so fashioned as to permit the bracket to move upwardly under the impact therewith of a knot, or the like, in the thread as it travels upward, and thus minimize the danger of breaking the thread, and also to permit the thread to move upward between the thread cleaning elements, to be described, at different points on their edges, to avoid wearing channels in them from long continued use.

The bracket 8 is held swingably in position by a pin or screw, preferably the latter, 9a, in the plate I, dotted lines, extended into a slot 10 in the tongue 1, to permit quick removal of the bracket when and if desired, instead of removing both cleaning elements, for instance, and the bracket is slotted vertically at H, or otherwise adapted to provide a thread and lint removing path.

The bracket 8 is tapped to receive screws [2, locking the cleaning disk elements l3 thereto. The truecircumferences, dotted lines, Fig. 3, of 5 these disks normally contact half-way between the screw centers l2, leaving no thread path, and the disks may have any desired number of facets l4, formed on the disk edges, each of which facets may be radially a dilferent distance from the disk center, and also a different distance from the true disk circumference, the latter, as indicated by characters l5 thereon, Fig. 3, to form a thread path. The disk I3 is provided on its lower face with a suitable locking device, as a slot [6, Fig. 1, to receive a pin ll on the bracket to positively lock the disk against rotary movement, in case the screw l2 should become loosened by vibration of the machine or other cause.

The facets l4, being different distances from the true disk circumferences as stated, that is, the midway point between the disk centers, will provide a path for the thread, in any case, equal in width to the distance between the facets, i. e., the sum of the fingers on the two disks adjacent 5 the facets cooperating to provide the thread path, the width being represented in any given unit of measurement.

In Fig. 3, the arrangement of the disks would provide a path It: thousandths of an inch in Width, and obviously this can be changed at will by using any combination of figures, provided by the disks, the greatest width obtainable in this case being 25 thousandths of an inch, and the narrowest being 11 thousandths of an inch.

By using a third disk, Fig. 4, with facets of different measurement, say one bearing the numeral. naught, with the facet 2 on one of the two disks shown in Fig. 3, a narrower path of two thousandths of an inch can be provided.

This invention provides, as illustrated, for the use of a thread as small as the usual mill uses, but to accommodate any mills which use a thread still smaller, an extra disk l8 may be provided, Fig. 5, having only one facet or thread cleaning edge M, which, when used with facet number one on the cooperating disk, will provide a thread path for a thread one thousandth of an inch in width.

Obviously, this member 18 may be of any desired shape, regular or irregular, and entirely operative, having only the number of facets or cleaning edges desired, but a curvilinear disk is most acceptable from the point of view of appearance.

In Fig. 6, I have shown a modified form of 5t cleaning member having one facet I4 marked with a radial distance from its center equal to one-half the distance between the screws I2, as is the facet 0 in Fig. 5, the outline of the remainder of the plate being unimportant, so long as it provides a slot for the lint, and preferably a forward guiding edge to cooperate with an adjoining facet to help guide the thread into the thread path. This disk may be adjustable or not, as desired, the important thing being that it provides one thread cleaning edge. Such a construc tion, of course, would provide only a limited number of paths, with different widths, when used with a second disk, but which might be sufficient for certain mills. It would simplify the work and decrease the expense of finishing one of the disks.

The foregoing construction provides a most novel, simple and ingenious device, compact, capable of adjustment to care for a tremendous range of thread sizes, yet rugged and quickly adjusted.

My invention is not restricted to the precise construction shown herein, but may be modified in many details, without departing from the spirit of the claims, and within the scope thereof.

I claim:

1. A thread cleaning device comprising a back plate with means for securing it to a support, means including forwardly and laterally extended arm-like members on the back plate, with an opening between them for the discharge of lint, a bra'ucketinsaidarin-likernembers,saidbrackethaving meansf or supporting cleaner members in axially centered position thereon, a plurality of thread cleaning members axially centered on the bracket, each cleaning member having a plurality of facets on its circumferential edge and of different radial measurement from the member center, each facet having means to indicate its distance in stated units of measurement radially from the true cleaner member circumference, and adapted to cooperate with said facets on a second similar member, to provide between them paths of different widths for the thread; means on the thread cleaner member supporting means, and on said cleaner member for locking said member to the supporting means.

2. A thread cleaning device comprising a back plate with means for securing it to a support, a bracket on said plate with axial centering means for fixedly supporting cleaning disks on the bracket in selective axial relation, tongue-receiving arms on the back plate, a tongue on the bracket vertically extended at an angle to the rear face of the bracket and loosely received in said arms, and a plurality of thread cleaning disks adjustable rotatively to cooperating relation with each other on said bracket, and thereby to provide a path of selective width for the thread between them, -each disk having one or more circumferential facets; each facet having a char acter indicating its distance from a circle described from its disk center with a radius equal to half the distance between the disk axial centering members, whereby the sum of the two numerals on disk facets opposite each other will indicate the width of the thread path between them.

3. Athread cleaning device comprising a back member with means for securing it to a support; bracket receiving arms on the back member; a bracket in said arms, with cleaning disk centering means thereon, a thread cleaning disk with cooperating centering means rotatably adjustable on said bracket, the disk having a plurality of facets on its edge, each facet being a different radial distance from the disk center and disk circumference; and identifying means for said latter distances on the disk; a member with a thread cleaning edge on the bracket cooperating with said thread cleaning disk edge to provide a path of selective width for the thread between them equal to that distance of the selected disk facet from the first-named cleaning edge.
